Shareholder Info

Top 20 Shareholders
About the Data

Data supplied by Morningstar and accurate on Aug 5, 2025.

It's not possible to publish a real-time Top 20 Shareholder list. Companies are not obliged to report this data (with the exception of Substantial Shareholders above 5%). If a company chooses to publish the data, it's usually once a year in their Annual Report.

All data is manually compiled so there might be a delay between the Annual Report being published and the data appearing on Market Index (<7 days for ASX 300 and up to 30 days for micro-caps).

Shareholder Distribution

As reported in the most recent Annual Report.

Holding Size 1 - 1,000 1,001 - 5,000 5,001 - 10,000 10,001 - 100,000 100,001+ Total

Substantial Shareholders

A substantial shareholder is a person or entity that owns 5% or more of the voting shares in a company. Shares can be held through multiple entities, so the Substantial Shareholders list differs from the Top 20 Shareholders list.

Shareholding changes less than 1% do not require notification to the market. When all “Last Notice” dates are identical, it suggests that no (or minimal) change has occurred since the most recent Annual Report.

Note: If a substantial shareholder's stake drops below 5%, the "Shareholders Selling" field shows full ownership as sold and sets "New %" to zero, even if they continue to hold shares under the limit.
